Packages are resolved on "resolved" phase just after "install" phase.
Framework creates "wires" between bundles using "Import" and "Export"
packages directives.
When exporting bundle goes away, importing bundle still holds references
to loaded classes until "update" or "refresh" will be called.
If you want to get more deeper into this process, you need to check
"OSGi Core Specification" chapters
3.7 "Resolving process",
4.4.6.3 "Restoring State After Refresh or Update"
4.4.9 "Updating Bundles".

Yes, though the spring bundle is just the single XML file loaded via the
fileinstaller.
I think my question should be the same for any two bundles that relate purely
by Import/Export packages:
At what point are the packages resolved?
What happens to that resolving when the Exporting bundle goes away?
Thanks

Subject: Re: Help understanding OSGi class loading
Hello!
I didn't understand clearly your task. Do you have one bundle with classes and
another bundle with spring xml file?

Hi,
I've just been surprised by the behaviour of karaf/felix and I'd be grateful
for some help understanding how this works.
My code is split into two chunks:
1. A compiled bundle.
2. A Spring XML file.
My intention is that the Spring file contains all the configuration relating to
the piece of work, whilst the bundle contains the (more static) compiled code -
with the intention of being able to update/replace the Spring file whenever I
want.
I just found an error in the bundle and uninstalled it, but the bundle created
for the Spring file is still running.
Does this mean that only OSGi services are dynamically removed, and if the
Spring file directly references exported classes from a bundle then the classes
are only resolved via OSGi when they are loaded?
In which case will restarting the Spring bundle clear it out adequately to
ensure that it picks up a new compiled bundle?
Thanks
Jim
